[marcelklehr]

Confirmed.

[AndyXheli]

Thank you for confirming! Should we disable the app or its okay to leave it on ?

[crocobc]

Confirmed also (same versions)

[Andreaux]

I am having the same issue.

[Andreaux]

Has anyone gotten closer to a cause or solution?

[marcelklehr]

The problem is that recognize depends on an OC API which, as opposed to OCP, is not public and thus not stable. In Nextcloud 25 and nextcloud 26.0.0 The getMetadata() Method was available, but since Nextcloud v26.0.1 it was renamed.

I suppose changing the code in recognize and dropping support for 25 would be the best past forward. We also don't need to drop support for 25 entirely, but have to confine it to a stable25 branch. I'll look into this tomorrow!

[Andreaux]

If there's anything I can do to help, I'd be happy to. Thanks for your help!
